- PETG and TPU users
- Smaller workspaces
- People who want a more organized filament setup
Potential downside:
- It is not as high-capacity as the S4 and not as advanced as the E2.

- One-printer setups
- PLA, PETG, and TPU users
- Users who want a compact dryer
Potential downside:
- It is not ideal if you need to dry several spools at once.
Check SUNLU FilaDryer S2
SUNLU S1 Plus Filament Dryer
Based on SUNLU product metadata checked on June 12, 2026, the S1 Plus was listed from about $39.99.
This is the budget dryer option for people who want basic moisture control without paying for a larger system.
Best for:
- Beginners
- Budget filament drying
- Basic PLA and PETG workflows
- Users who want a simple dry box
Potential downside:
- Advanced users may outgrow it quickly.

SUNLU UV Resin Curing Box RC-2
Based on SUNLU product metadata checked on June 12, 2026, the RC-2 was listed from about $49.99.
This is not for FDM filament users. It is for resin printing workflows where curing quality affects final strength, surface finish, and durability.
Best for:
- Resin printer owners
- Miniature printing
- Functional resin parts
- Users who want more consistent post-curing
Potential downside:
- It does not replace washing or safe resin handling.

1. Wide filament selection
SUNLU covers far more than basic PLA.
You can find PLA, PLA+, PETG, ABS, TPU, silk, matte, wood, marble, glow, carbon fiber blends, high-speed materials, engineering filaments, refill filament, and large spools.
That makes the store useful whether you are a beginner or a regular 3D printing user.
2. Strong value for frequent printing
SUNLU is known for accessible pricing.
If you print often, the cost of filament matters. Refill filament, bundle deals, and large spools can help reduce material cost over time.
3. Filament dryers are a real strength
Many filament brands sell filament only. SUNLU also sells drying hardware.
This matters because moisture is one of the most common causes of bad prints, especially with PETG, TPU, nylon, and carbon fiber blends.
4. Good options for Bambu and multi-material users
SUNLU's AMS Heater is aimed at Bambu AMS users who want drying while printing.
That is useful for people running multi-color or multi-material workflows.
5. Free shipping to many regions
SUNLU states that it offers free shipping to most countries and regions, including the USA, Europe, the UK, Canada, and Australia.
Shipping policies can change, so check your country and cart total before ordering.
1. Product catalog can feel overwhelming
There are many filament categories, dryer models, and accessories.
This is good for choice, but beginners may not know whether to buy PLA, PLA+, PETG, high-speed PLA, refill filament, or a dryer.
2. Prices and promotions change often
SUNLU runs sales, bundles, and auto-discounts.
That can be good for deals, but it also means you should verify the final checkout price before deciding.
3. Not every product is for every printer
AMS accessories, large spools, refill filament, engineering filament, and resin tools all require compatibility checks.
Before buying, confirm your printer, spool holder, AMS system, nozzle, enclosure, and material requirements.
4. Advanced materials still require tuning
Buying carbon fiber, nylon, PETG, TPU, or engineering filament does not guarantee perfect prints.
You may still need to adjust temperature, drying time, bed adhesion, print speed, enclosure conditions, and slicer settings.

SUNLU is worth buying from if you want affordable filament and practical 3D printing accessories from an official store.
For most beginners, start with SUNLU PLA or PLA+. If you print functional parts, add PETG. If your prints show stringing, popping, brittle filament, or inconsistent extrusion, a filament dryer like the S2 or S4 is worth considering.
For frequent printing, SUNLU Refill Filament and larger spool options can help reduce cost and waste.
For advanced users, the FilaDryer E2 and engineering filament categories are more relevant, but they require more tuning and printer preparation.
Best picks by use case:
- Beginner filament: SUNLU PLA or PLA+
- Budget refill option: SUNLU Refill Filament
- Basic dryer: SUNLU S1 Plus or S2
- Multi-spool drying: SUNLU FilaDryer S4
